Hi all,
I noticed that the Transport for Wales train route Cardiff <> Holyhead was completely missing from OSM. (Reason being, I’m involved in a different project which relies on the routes being there in OSM.) So I’ve created the relations and started going East & south from Holyhead, applying the relations to all train tracks.
My main question is this:
I’m doing this in ID editor, and the going is pretty slow – selecting a couple of pieces of track (or rather, their ways), applying the relation, then doing the same thing for the opposite line, then moving further down the map. Is there a faster way? It’s very Zen, and over the xmas period I do have a few days for this – but ordinarily I wouldn’t do it at all if I didn’t have this much spare time.
I’m thinking something like automatically selecting all connected track pieces in one direction up until the next set of points, because only at the next set of points is it usually required to make an informed decision on how to continue. If something like that were possible, that would be very useful.
JOSM is generally the recommendation for editing large relations. I find the icons for adding elements in the relation window a little un-intuitive, but it’s generally quite good.
It also has an option to “Select non-branching way sequences” (Shift+W), which might be helpful. I don’t know how all the ways are mapped but it may be possible for a way to continue through a set of points so you might need to keep a eye out for that.
If you enable advanced editing mode you can download using overpass queries to selectively download only the data you need and exclude the rest. This can be useful for edits over large areas but I wouldn’t recommend this if you’re new to OSM as it’s quite easy to accidentally modify something in a way that’s incompatible with the data you didn’t download unless you’re really careful (some of the automated warnings may lack the context they need to operate too).
I have just spotted this and I feel I should point out that you will need to describe to ans discuss this different project to/iwth the UK community. Here is fine.
The other project is the Indoor CO2 map (https://indoorco2map.com/) to record the air quality in publicly accessible indoor spaces.
Open Source and non-profit. It’s not my project, but I’m doing some beta testing.
It’s expanded its scope to recording the air quality on public transport, though at the moment the visualization of that data is minimal. It’s because I recently traveled on the aforementioned route, and wanted to record air quality data using the app, that I noticed the route was completely missing on OSM.
Thanks, I’ll look into the possibility of limiting the downloaded data with Overpass queries. Didn’t know that was a possibility, but it sounds just like what I’d need. I’ve already been using Overpass manually to try to understand things about the existing lines.
